Hi there,
I also would think that your lo will still need the df for a little more time. I just dropped my los around the 7.5 month mark.... and I did it cold turkey...
I thought I would wait to see if he woke up, and he didn't.
You could time how long your lo usually nurses at that time and slowly shorten down the amt of time. That would be the way to compensate instead of counting oz on the bottle.
But again, you may want to hold off just a little longer. But you know better than anyone what your lo is capable of.
HTH
